To all whom it may concern.-

Beit known that I, PAUL R. DEF. Dl-IUMY, a citizen of the Republic ofFrance, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Apparatusfor Electrolytically'lreating Raw Hides, of which the following is aspecification.

This invention relates to an improved machine for treating raw hides,leather and analogous substances, and consists in certain peculiaritiesof the construction, novel arrangement, and operation ofthe variousparts thereof, as will be vhereinafter more fully set forth andspecifically claimed.

The object of my invention is to providea machine for the above namedpurpose, which` is simple in construction andv reliable and effective inuse, and will automatically reverse its movement.

In order to enable others skilled in the art, to which my inventionpertains to make and use the same, I Will-now proceed to describe it,referring to the accompanying drawings, in which` f Figure 1, is a Viewin sideelevation of ,my machine as it appears when ready for opera#tion. Fig. 2, is a plan sectional view thereof.' Fig. 3, is a view inside elevation partly in section showingsome of the rollers or bars of;the treatingv drum removed. Fig. 4, is asimi# lar View of the treatingcylinder and rollersk or bars, showing the raw-hides in place and in theact of being treated or acted upon.' Fig. 5, is a plan View of the upperplate of the ,treatingdrum and the cylinder, and Fig. 6 isan enlargeddetail sectional view of the lower portion of the sleeve and its fiange.

vSimilar letters refer to like parts through# out the different views ofthe drawings.

A, represents the main or supporting frame, which rests on a suitablebase or door, to which is secured the various parts of the ma-y chinery,andin which the several shafts ory journals have their bearing. To thatportion of the supportingframe, which hasv the doorl a, is secured in ahorizontal position 'on the upper surface of said floor a plate a',through suitable openings in which are passed and se-- cured a number ofstandards or upright posts a2, which have secured at their upper ends a4plate a3, of substantially the same construction and form as the'platea'. Throughthe cent-er of each of the plates c', and as, is formed anopening, in the former named plate, for the reception and operation ofthe Asis clearly seen in Figs. l, and 3, of the drawings, the lowerportion of the cylinder B, extends through the floor a, and is providedwith a horizontal beveled cogged gear D, which engages with beveledpinions d, and d', which pinions are suitably mounted on vthe Operatingor main shaft D', which shaft has its bearings in suitable journal boxesd2, on the main or supporting frame, and extends some distance to .oneside of the horizontal gear D, and the treating drum and its cylinder.On this extended portion and adjacent to the pinion d', is mounted agearE, which meshes with the. gear E', mounted on the shaft F, whichshaft is located parallel with the driving shaft D', and atl one sidethereof in suitable'journal boxes d2, on the main or supporting frame...Near the gear E, and on the shaftD, is another gear E2, which engageswith'a pinion or gearF,on theshaft F, as is clearly/seen in Fig. 2, ofthe drawings. To one side of the gear E2, and near its outerend the`shaft D', is formed or provided with a screw-threaded section D2, withwhich engages a traveler or nut D3, whichis forined'or .provided with anarm d3, the upper end of which is'secured to a horizontal bar d4, whichis adapted to slide `or move horizontally with with a horizontal slidingbar e, on the inner end of which is provided a belt-guide e', and

which bar is retained in a horizontal positionv by means of brackets e2,secured to the supporting frame. Between the gears F', and E', on theshaft F, is mounted three pulleys H, H', and H2, the pulley II', being aloose pulley, and the one H, keyed to or fixed upon the shaft F, whilethe pulley H2, is rigid with the pinion or gear E', which gear isloosely Journaled on the shaft. The gears E2, and F', and pinion CZ, arekeyed to or rigidly iixed on their respective shafts, but the gear E,and pinion d', are loose on the shaft D', but are rlgrdly connectedtogether thus permitting the reverse motion of the machine, as will bepresently explained.

As before stated the cylinder B, is provided with a vertical slot B2,for'the reception of the raw-hides, which are secured in said slots bymeans of suitable set-screws c, which are located in holes or openingsin the cylinder at the desired point. These openings c', arc of sufcientsize to admit of the insertion of a wrench or other suitable device fortightening the screws, which screws when tightened, are counter-sunk inthe cylinder, so as to offer no obstruction to the movements of thesleeve B', which is provided at its lower end with an annular flange B2,which flange extends from the periphery of the cylinder to the innersurface of the rollers or bars C, and af? fords a vertical pressure onthe raw-hides. The upper end of the sleeve B', is provided with a hookor ring b4, to which may be secured a rope which may operate `over apulley when it is desired to raise the sleeve. As the sleeve may nothave suficient weight to give the desired amount of vertical pressure, Imay place across its top a bar C3, which may be weighted at one end andadjustably secured to a post C, at its other.

As is clearly seen in Figs. 4, and. 5, the in ner surface of the sleeveB', is provided with an insulation M, which extends from its top to itsbottom, and that the flange or 4disk B3, thereof, is also provided withan insulator M', around its periphery, which as before stated extends tothe inner surface of the rollers C, which rollers are provided with aninsulation, both at their upper and lower ends in the sockets within theplates a', and a2, which are located `as before set forth.

To the upper portion of the sleeve B', is connected by means of asuitable binding-post or terminal 'm,awire N, which leads from said l atm3, to prevent the current of electricity passing through the same.

In the event of the inoperation of the current of electricity throughthe wire N, at the top of the sleeve B', I may connect another wire N2,leading to the same pole of the battey, to the lower part of thecylinder B. In order to prevent the current of electricity from passingfrom the horizontal gear to the operating mechanism, the teeth or cogsof saine may be made of any suitable non-conducting material.

The operation of my device is simple and as follows: The sleeve B', israised so as to expose the slot or a portion thereof 1n thecylinder B,and a number of hides are inserted and secured in said slot by means ofset-screws c. The power is then applied to the machine by means of thebelt f, which passes over the pulley H, and a power-pulley (not shown),and as the pulley II, is rigid on the shaft F,

it will cause the same to revolve, in which `operation the pinion F',meshing with the gear E2, transmits the rotary motion to the shaft D',which being geared to the horizontal cogged-wheel D, by means of theplniond, will impart its motion to the cylinder B, and cause the hidesc10 to beiwound thereon, and to be compressed by reason of the rollersG, which as before stated are placed in a `circle around the cylinder,and in order to prevent injury to the hides by reason of friction, arepreferably loosely secured in the plates a', anda, and at the same timethe sleeve B', by reason of its own gravity or that 'of the vbar C2,when used, will afford vertical pressure 'on the hides. In the movementof the machine described, the traveler or nut D2, will glide forward onthe driving shaft by reason of its screw-threaded connection, and willcause the lever which engages with the bars e', ande?,

to assume the position indicated by dotted lines in Fig. 1, when thebelt f, will be forced IOC thereby from the pulley H, to the pulley H2,

which being rigid with the pinion E', which pinion is loosely journaledon the shaft F, and engages with the gear E, which is rigid with thepinion CZ', will impart a reverse mo,- tion to the horizontal gear andthrough it to the cylinder, and at the same tirnethe traveler D3, willbe returned to its normal position and through its 4connections with thetraveler, the lever will again cause the belt to shift `back to thepulleyh, when theoperation before described may be again repeated.

In the above stated operation 'the current of electricity is turned onandcarried `through the sleeve B', `from which it passes into `"andthrough the hides, which may havebeen moistened -to make them abetter'conductor, 'thence through the rollers C, and over 'the wire N',or the alternative course 'may be taken. The electric currentpassingithroughthehidesdevelops a gentle heat, `:and assists inthezdisintegration and separation of thefattyfibrin contained iu thehides, and facilitates randacA celerates the penetration of the`component liquor therein,which quickly ren ders the same pliable,elastic, and silky, by reason of the mechanical and electrical action towhichthey have been subjected.

Having thus fully'described my invention,

what I claim as new, and desire to secure by Letters Patent, is
